[SOLVED] vec_for_screen camera shaking - 05/30/16 12:04

Hi,

I use vec_for_screen to position several entities for the game interface.
But for some reason the vec_for_screen line in the code below results in that the entity constantly switches position a bit (as if it is a vibrator lol

). camera constantly changes position.

Code:

while(1) {
vec_set(my.x, vector(50, 50, 0)); // x/y test values
my.z = 50; //depth
vec_for_screen(my.x, camera);
vec_set(my.pan, camera.pan);
wait(1);
}

Besides that shaking, the camera itself stands still by the way.
If I comment the line "vec_for_screen(my.x, camera);" out, the problem goes away. But I would like to use vec_for_screen obviously.

Oh stupid me, the inventory slots were catched by a trace for the camera code.

I will leave this thread here cause I quess its easy to make this mistake.

And for all beginners facing this problem,

Code:

c_ignore (...,0);

and

Code:

my.group

can help here ( besides PASSABLE and IGNORE_PASSABLE flags ).

I might as well give another tip now, you can use Define for 'groups' too to make your code cleaner and better readable, example:

Code:

//collision groups
#define ALLY_GROUP	1
#define ENEMY_GROUP	2
#define NATURE_GROUP	3
#define ITEM_GROUP	4

....
action squirrel() {
   my.group = NATURE_GROUP;
   ...
}

function convert_squirrels() {
   c_ignore(ALLY_GROUP, ITEM_GROUP, 0); //only enemies or nature
   if (c_trace(..., ..., ...) > 0) {
     if (you) you.group = ALLY_GROUP;
   }
}

Maybe a bit offtopic though
